Mike,

I hope you find an answer to this. We have a similar requirement with a Web Service to Login to our application. One of my co-workers is in the process of researching and developing this and he hit a brick wall yesterday.

If he finds a solution, I'll let you know. If *you* find a solution, let *me* know. =0)
